(continued)For example, when a Volume formula is created:
Vol [ml or cm3] = 0.523598*{D1}*{D2}*{D3}
(D1, D2, and D3 indicate a measurement result.)
In this case, the measurement (D1, D2, and D3) is a distance 
measurement, so the measured data is a meter [m] unit 
according to the above table. 
To change into a milliliter, the system multiplies each 
measurement value by 100. As a result, it multiplies a formula 
by 1,000,000.
The standard unit of volume is a cube meter, so the system 
multiplies the result by 1,000,000.
The system multiplies the calculation result by the coefficient 
and converts it. To get a correct result, when you define the 
formula, you must convert the coefficient itself, such as the 
coefficient of 10^.
For example, if you want to define the following formula: 
efg[g] = 10^(1.5662-
0.0108*{P1}+0.0468*{P2}+0.171*{D1}+0.00034*{P1}*{P1}-
0.003685*{P2}*{D1})

(continued)The system defines the standard value of each measurement as 
a meter [m]. If the unit of each measurement value of this 
formula is defined as centimeter [cm], you must define the 
formula as follows:
efw[g] = 10^(1.5662-0.0108*{P1}*100 + 0.0468*{P2}*100 + 
0.171*{D1}*100 + 0.00034*{P1}*{P1}*100*100 - 
0.003685*{P2}*{D1}*100*100)
(This converts each measurement value to a centimeter [cm], 
since the system standard unit is a meter [m].)
The output unit of this formula is a gram. Since the standard unit 
of the system is defined as a kilogram [kg], the system multiplies 
the output by 1,000. 
Because the output of this formula is defined as a gram, it is 
necessary to define the formula as follows.
efw[g] = 10^(1.5662-0.0108*{P1}*100 + 0.0468*{P2}*100 + 
0.171*{D1}*100 + 0.00034*{P1}*{P1}*100*100 - 
0.003685*{P2}*{D1}*100*100)/1,000
As shown, you can obtain an exact calculation result.
